Diodes in SEG LED TV

[Murphy Maniac]

Returned from Golborne armed with suitable Schottky Diodes, kindly supplied by Keith, and had another good look around following your comments. Looking more carefully under a magnifying glass, D11 has indeed got ferrite beads on each end held together with green gunk, tests OK as well. I intend to replace it anyway and hope for the best. As you so rightly point out, the boards are cheap enough to replace en bloc rather than messing about testing and replacing all those dodgy foreign electrolytics.
Many thanks for all your helpful advice, I will post the result when I get the replacement diode for D11.
Best Wishes to all,
Geoff.
